Frequency inverters DF51
vector frequency inverters DV51
Application
The frequency inverters of the DF51 series provide infinitely variable speed control
of three-phase motors. They are especially suitable for applications where simple
operation and economic efficiency are important.
The assigned performance range for four-pole three-phase asynchronous motors
ranges from:
• 0.25 to 2.2 kW with single-phase power supply (230 V)
• 0.25 to 7.5 kW with three-phase power supply (230 V)
• 0.37 to 7.5 kW with three-phase power supply (400 V)
The frequency inverter DF51 can be used as a stand-alone drive or incorporated in
automation systems. With its / (voltage/frequency) characteristic control, it can be
used in wide range of applications, from simple pump and fan drives through
standard transportation and conveying applications to flexible use the machine tool
and packaging machine industry.

Additional operational functions:
• > 100 % starting torque from about 6 Hz
• PID controller
• Automatic voltage control (boost)
• Min./max. frequency limitation
• Electronic motor potentiometer function
• Frequency hopping (frequency masking)
• DC braking to motor standstill
• Up to 16 fixed speeds
• PLC functionality: Linkage of digital in- and outputs
Documentation
• Each DF51 vector frequency inverter is supplied with installation instructions
and a CD.
• The AWA contains a short description with illustrations and information about
correct handling, installation and electrical connection of the device. The
information supplied is printed in seven languages (English, Chinese, French,
German, Italian, Russian, and Spanish).
• The CD contains a detailed manual (at least English, German) and configuration
software with help text.
• Documentation and parameterization software are also available for download
from the Internet:www.moeller.net/support
Note:
The software on the CD can be run on PCs with the current Windows operating
systems (from 98 to XP). For connecting a PC (RS 232) to a DF51 frequency inverter,
you will need the connection cable DEX-CBL-2M0-PC.
